Abstract: Different genes might be involved in Colletotrichum lindemuthianum resistance in leaves and stem of common bean. This work aimed to study the genetic mechanisms of the resistance in the leaf and stem in segregating populations from backcrosses involving resistant cultivar AN 910408 and susceptible cultivar Rudá inoculated with spore suspensions of C. lindemuthianum race 83. Our results indicate that two genes which interact epistatically, one dominant and one recessive, are involved in the genetic control of leaf anthracnose resistance. As for stem anthracnose resistance, two genes also epistatic, one dominant and one recessive, explain the resistance to C. lindemuthianum race 83. The recessive gene is the same for leaf and stem resistance; however, the dominant genes are distinct and independent from each other. The three independent resistance genes of AN 910408 observed in this work could be derived from Guanajuato 31.
